HCPL2531M

Single-Channel: 6N135M, 6N136M, HCPL4503M Dual-Channel: HCPL2530M, HCPL2531M — 8-Pin DIP High Speed Transistor Optocouplers January 2016 Single-Channel: 6N135M, 6N136M, HCPL4503M Dual-Channel: HCPL2530M, HCPL2531M 8-Pin DIP High Speed Transistor Optocouplers Features High Speed – 1 MBit/s Dual-Channel: HCPL2530M, HCPL2531M CTR Guaranteed 0°C to 70°C No Base Connection for Improved Noise Immunity (HCPL4503M) Superior CMR of 15,000 V/μs Minimum (HCPL4503M) Safety and Regulatory Approvals – UL1577, 5,000 VACRMS for 1 Minute – DIN EN/IEC60747-5-5 Applications Line Receivers Pulse Transformer Replacement Output Interface to CMOS-LSTTL-TTL Wide-Bandwidth Analog Coupling Description The 6N135M, 6N136M, HCPL4503M, HCPL2530M, and HCPL2531M optocouplers consist of an AlGaAs LED optically coupled to a high speed photodetector transistor for each channel. A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor. The HCPL4503M has no internal connection to the phototransistor base for improved noise immunity. An internal noise shield provides superior common mode rejection of up to 50,000 V/μs.
